Y of the axle and wheel or pulley, in a direc*- tion in the plane of thewheel or pulley, the axle always being parallel to its normal position,and the arrangement being such that parts are nevertheless eiticientlysupported or guided as is necessary. For this purpose, according to theinvention there are interposed Ibetween the axle and the wheel telly atleast two eccentrics located one within the other and one of which ismounted on the axle. The eccentrics are associated with springs whichtend to maintain the ecoentricity, in the case oit two eccentricscarried within each other, approximately horizontal for example, sotliat'the'Y axle can only execute a vertical movement. Various examplesof axle bearingsV embodying the invention are illustra-ted in theaccompanying drawings. y

vis another modiication of the arrangement Fig. 25

Fig. 33 illustrates an arrange-y Ainvention can be constructed inseveral dit'- ferent ways, for example, one arrangement may comprise anumber orl what may be called eccentric bearing rings 2, 3 and 4l or thelike supporting each other by means of ball bearings 1, the innermosteccentric bearing ring running with suilicient freedom on the axle.

The eccentric rings can either be free to revolve around each other, ormay be connected by any suitable means. When the rings are connected bysprings or other yielding means the connection is such as to allowwithin certain limits the desired selfadjusting mutual movement oftherings.

The purpose of the eccentric bearing rings is, as hereinbefore stated,to give the axle the power of a flexible movement in a directionperpendicular to the axis of the axle, while it always remains parallelto its normal position, and at the same time 'to effectively guide orsupport the parts during the movements. At the same time, in order toproperly counterbalance the movement of the axle, or in other words, toregulate the centralization without preventing the shifting necessaryfor smooth and easy running, flexible elastic or spring devicesconnecting the rim to the axle 5 are provided, the said devicesconsisting for example of springs 6.

Springs 6 projecting radially from the rim 7, as shown in Figs. 1 and 2,can be connected with the axle either outside the eccentric bearingrings, or by members passing loosely through holes formed in theeccentric bearing rings. In the latter case the connecting members canconveniently be constituted by rods 8, the outer ends of which areassociated with the springs 6 and the inner ends of which are directlyassociated with the axle, as by means of free running rings 9 (Fig. 2)on the latter lo cated at regular intervals along the length of theaxle, so that the rods 8 are located at diferent distances from the endsof the hub around the circumference of the wheel.

The wheel arrangements shown in Figs. 1 to 6, partly through theeccentric bearing rings supporting the axle, and partly through theflexible or spring attachments connecting the axle to the wheel rim, aresuch that, should the eccentric bearing rings or the lexible or springattachments become useless, the wheel can still work because the axlewill be still held in position although not in concentric relation tothe wheel rim. For instance, should the springs break, the

axle can at the most only be brought from the center a distancecorresponding to the total eccentricity of the several eccentric bearingrings. 1n addition to the drive being transmitted through the rods 8striking the ends or" the slots in which the rods work and whichrestrict their movement, the restricted reciprocal movement of theeccentric bearing rings can be produced, as shown in Fig. 3, by spiralsprings 10 arranged to connect each two adjacent eccentric bearing ringswith each other; or, as shown inFigs. 4, 5 and G, one or each eccentricbearing ring can be provided with a nose 11 adapted to strike against astop or shoulderi 12 on an adjoining disk. Springs 13, see Figs. l and5, may be associated with the stops 12 to modify or cushion the blows.rlhe arrangements or the restriction of the relative movements of theeccentric bearing rings are intended to prevent all the eccentricbearing rings simultaneously assuming such a position that the axlecomes, so to speak, to a dead lock, which does not happen if theeccentric bearing rings or eccentric centers are right above each other.As shown in Fig. 1, it is convenient to place the springs 6 in tube-likeguides 14 that extend radially from the inside of the wheel as by thisarrangement the springs are efliciently protected. A

Vilith an arrangement such as shown in Figs. 7 and 8, where theeccentric bearing rings are replaced by eccentric` cylinders 2 and 3 itis possible, by means of ball bearings located beside each other,v toobtain with eccentric cylinders orp comparatively small diameter thesameeccentric effect as with eccentric bearing rings of quite large d1-ameter where the ball bearings are arranged one over another. When sucheccentric cylinders are used the outer or larger cylinders mustbeshorter than the inner or smaller ones. rlhe ends of the cylinders areprovided or formed with flanges or collars 15 which give support to theconcave ball bearing rings 16.

1n the arrangement or construction of belt pulley shown in Figs. 9 and10, the eccentric bearing ring 2 runs free on a sleeve 16 ixed on theaxle, ball bearings being interposed. Mounted on the eccentric bearingring 2 is the hub 1'? of the belt pulley, ball bearings beinginterposed. Fixed as by screwing or the like, on one end of the sleeve16 is a disk 18 which is connected with the -belt pulley rim 20 by meansof an arrangement et springs 19. For tensioning the belt a springweighted arm 21 is provided. Several series of eccentric bearing ringsor cylinders can be arranged over one another on the axle to stillfurther increase the eccentricity. Thus eccentric bearing rings can bearranged on a sleeve fixed on the axle, the said sleeve being providedwith a liange that can be connected with the wheel rim by means ofsprings. In one arrangement of axle bearing, according to the invention,one or several eccentric bearing rings is or are connected to the axleby springs. Each spring can be associated at one end with and run alongthe circumference of the ring and be suitably stressed. 1nV anotherarrangement two eccentric bearing rings are connected with each other bymeans of a spring suitably associated with the periphery of the Outerbearing ring.

Figs. 11 and 12 show the invention applied to a motor car wheel, where,as in previously described arrangements, springs connect the wheel rimwithV the 'axle 5. These springs are pivotally connected with disks 22and 23 fitted on the axle, the disk 23 being connected with a brakewheel 24. The disk 23 is in one piece with the axle socket or sleeve 25and the disk 22 is fitted on such socket or sleeve. A. key, and a nut26, fixes the socket or sleeve 25 to the axle. rlhe before mentionedspring arrangement consists fo-r each spring of a cylinder 27 pivotallyconnected with the wheel rim and to which isconnected one end of a rod28 whose other end is connected with the axle by means of disks, such as22 and 23, through a cross piece 29.

Figs. 13 and 14 show the invention applied to a cycle wheel. In thisarrangement two eccentric bearing rings 2 and 3 are each connected bymeans of a projection 30 or 33 integral or fixed to it to a spindle y3101234 by means of a link 32 or l35 that is adjustable lengthwise. Thespindles 31 and 34 are mounted in side members of a lever arm 38 keyedto the axle 5 and projecting through slots in the eccentric bearingrings 2 and 3. The portions of the spindles 31 and 34 between the sidemembers of the arm 38 are squared and are encircled by a leaf spring 36and 37, respectively, whose other extremity is wound on a lateralprojection of links 32 or 35. 1n order to prevent an excessive strain onthe springs k36 and 37 in case of a severe jolting the spindles 31 and34 are mounted rotatably in the side members of the arm 38 and eachspindle is fitted with an arm 39 or 40 which is associated with ahelical spring 41 and 42. These springs are connected with the lever 38,as shown. The whole system of springs and connections is only for thepurpose of holding the eccentrics in a normal position and so centeringA the axle, and may be mounted together with the eccentric bearing ringsin the hub of a cycle wheel.

The operation of the device is as follows:

Assuming that a bicycle provided with they improved bearing arrangementis on an uneven road and that an obstacle meets the wheel from below sothat this latter moves upward in the direction of they thrust. The

axle ltends to move in an opposite direction, z'. c. downward toward thepoint of the thrust. When the axle moves downward the smaller eccentric2 will be forced to rotate toward the left, that is, counter-clockwiseand the link 32 will be brought to a position indicated in dotted linesin Fig. 13.

parallel to its normal position. Because theV links 32 and 33 are alsoconnected to the springs, the latter will be more and more stressedduring the entire rotary movement of the eccentric bearing rings andconse-V quently of the links, whereby they tend to bring the eccentricsand the axle back intoy the starting position. 1t is obvious that thesprings do not, therefore, have a supporting. function, but only thepurpose of effecting the return of the axle to its normal position afterit has been displaced under the influence of a sudden jolt or thrust.The upward and downward vertical movements of the axle against thetendency of the springs to bring the former back into normal positionproduce a yielding or elastic vertical oscillating movement of the axle,so that a solid wheel tire may be employed instead of a pneumatic one. Y

Fig. 15 is a diagram illustrating an application of an arrangementsimilar to that last described. rlhe springs 41 and 42 are replaced byweighted arms 43 and 44 connected with the corresponding spindle spring31 or 34. 1n some cases, and if desired, both the -springs 41 and 42 andthe weighted arms 43 and 44 can be used simultaneously.

According tothe arrangement diagrammatically indicated in Fig. 16 thespring arn rangement 31, 34, 36, 37, 41, 42, 43, 44 is replaced by afiat or leaf spring 45, the ends of which are connected to links 32 and35 and the middle portion of which is supported by an arm 38.

The arrangement diagrammatically indicated in Fig. 17 differs from thatof Fig. 16 only in that the leaf spring 45 is replaced by a cross stay46 fixed to the arm 38v at its middle portion and connected at its endsto springs 47 and 48, which are connected 2 and 3 coupled together by ahelical spring 51 wound around the periphery of the outer bearing ring 3and connected at one end to one said ring and at the other end to theother ring.

Fig. 21 illustrates three eccentric bearing rings 2, 3 and 4 withhelical springs 52, 53 and 54 wound around them. The spring 52 is woundaround the innermost bearing ring 2 and has one end fixed to the saideccentric bearing ring and its other end fixed to the eccentric bearingring 3; the springV 53 is wound around the ring 3 and has one end fixedto such ring, its other end being fixed to the ring 4 while the spring54 is wound around the bearing ring 4 and has its one end fixed to saidring and its other end fixedy to the axle 5 by means of an arm 38.

Fig. 22 indicates an arrangement similar to that shown in Fig. 21 butthe springs 52 and 53 of the bearing rings 2 and 3 respectively, insteadof being attached to the adjacent eccentric bearing rings, are directlyattached to the lever arm 38.

In the arrangement shown in Fig. 23, the eccentric bearing rings 2 and 3Aare sup ported as by means of ball bearings in a ring 61 around whichthe wheel rim (0 is in its turn mounted to revolve, most suitably oninterposed ball bearings. The ring 61 sugports the axle 5 by means of asupporting bracket 62. The axle 5 is effectively guided in the bracket62 by means of a guideway suitably consisting of two side members 64 and66 and is resiliently supported by means of a spring 63. The axle 5 isalso connected to the carriage by means of springs, not shown, or bybracket supports 67, 63, which are suitably fastened at their lower endsto al bearing block or axle support 65. The weight of the carriage onthe wheel is thus transferred through the bracket supports 67, 68, theaxle support 65, the spring 63, the bracket 62, and the ring 61, bywhich means the transfer of force from the axle to the wheel, and viceversa takes place without the eccentric bearing rings, which are locatedinside the ring 61, sustaining any severe shock. The said eccentricbearing rings 2 and 3 are thus exempted from acting as supports, but onthe other hand they serve to efficiently guide the axle. Thisarrangement even permits of the eccentric bearingrings themselves notbeing guided as they are sufficiently guided by the ring 61 on the onehand and the axle 5 on the other.

In the arrangement shown in Fig. 24,

ydistinguished from that just described, the

supporting bracket is constituted by a spring 63 attached to the ring 61and to the axle 5 or axle bearing 66. The connection with the ring 61can be by means of links 74. The connection with the body 79 of thecarriage y' canl be not only as described with reference to Fig. 23, butmay be through a spring 75,

for example, or through several such springs which may be of leaf,helical or other type. ln the example under notice the attachment of thespring to the body of the carriage is by means of links 76 andsupporting brackets 77'. In order to give support to the axle and to thewheel in a horizontal direction a supporting piece 73 can be attached tothe body of the carriage.

Fig. 25 shows in the main a similar arrangement to that of Fig. 24, themain difference being that both the springs 63 and 75 are placed abovethe axle 5 and that the supportJ for the axle in a horizontal directionis omitted.

ln the arrangement shown in Fig. 26 the axle 5 rests on a leaf or bladespring 63 which is connected with the wheel hub by links or stays 74.The axle support 66 is of the shape shown.` y

According to the arrangement shown in Fig. 27 the spring 63 is replacedby bent brackets 8O or the like, which by means of a spring arm 31,*orarms, is attached to the ring 61. rlhe spring of the .arm 31 can, asshown for instance be provided for by helically twisting the middleportion 82 0f the arm. The arms 31 are pivoted Vat 81a to the ring 61and the bent vbrackets 8O are pivoted at 8()a to the Vaxle bearing, asshown.

According to the arrangement shown in Figs. 28 and 29, which represent awheel adapted to be driven by motor power, for instance a motor carwheel, the axle bearing 66 is fixed toV an axle socket or sleeve 33which encircles the axle 5. The supporting spring72 is arranged on thesocket or sleeve 83. A spring 63, which is associated with the bearing65, is carried in a bracket 62 fixed to the ring 61. The innermost ec-Vcentric bearing ring 2 is mounted to rotate in bearings around the axlesocket 0r sleeve 33. At the. outer end of the axle 5 is a disk or thelike 84, provided with one or several spring arm brackets 6 which areconnected to the wheel rim 7. By the transference of power from the axle5, through the disk 84 and springs 6, the wheel 7 is rotated. 85 is abrake drum which may be fixed on the said stay, disk, or ring 84.

Fig. 30 illustrates an arrangement that resembles theV arrangement lastdescribed in that the eccentric bearing rings run in bearings on thesocket or sleeve 33, but the ring 61 and its attendant combination, suchas bracket 62 and axle support 66, etc., are omitted. As in the previousexample the driving power is transferred from the axle 5 to the disk 84,and thence to the wheel.

Fig. 31 shows in central horizontal section an arrangement of the kindunder notice with eccentric bearing rings wherein the power istransferred through cog-wheel or chain gearing to the rim. As in some ofthe arrangements previously described there is tted on the axle 5 a tubeor sleeve 83 to which a disk 3s or the like of the kind previouslydescribed is fastened, Which is connected to the rim by means ofsprings. rlhe chain Wheel 36 or the bevel Wheel 87 is iixed on the tubeor sleeve 83. This construction can for instance be used for cycles asthe power from the chain Wheel 86, or the toothed Wheel 87, istransferred to the sleeve 83, and thence through the disk 811 to therim. On 'the sleeve 83 or the disk 811 a brake drum can be attached. Thechain Wheel 36 can be arranged on the periphery of the toothed Wheel. Inthis case the axle 5 is lirmly connected to the carriage and the tube orsleeve S3 can freely rotate on the axle 5.

Fig. 32 is a side elevation of the arrangement shown in Fig. 31.

Fig. 33 illustrates an arrangement Wherein the springs which unite theeccentric bearing rings 2 and 3, are attached outside the hub of theaxle.

Fig. 34 shows an eccentric bearing ring 2 with the axle, the bearingfor'the said ring being at the periphery of the ring. Projecting fromthe eccentric bearing rings are arms 88 connected by an arrangement ofsprings 39 which are connected With the axle 5 by an arm or bracket 90.One of the arms 88 is connected to the eccentric ring 2 and the other tothe eccentric ring 3.

ln the arrangement shown in Fig. 35 the eccentric bearing rings 2 and 3are maintained in the desired relative positions by springs 91 and 92Which are connected by means oit links 93 and 9-1, kthe ends of thespring 92 being free from the rings. The springs 91 and 92 are connectedWith the axle 5 by a cross stay 95.

rl`he arrangement shown in Fig. 36 diiiers from that shown in Fig. 35 inthat only the spring 92 is coupled to ythe axle 5 by the cross stay 95.The ends of the spring are coupled to the eccentric bearing rings 2 and3 by means of links 93 and 94, as previously described.

The arrangement shown in Fig. 37 diiers from that shown in Fig. 35 inthat the spring 92 is reversed in position and is attached to the spring91 Without links, by means of pivot pins, one of Which is connected tothe eccentric ring 2 and the other to the eccentric ring 3.

In all the arrangements described with reference to Figs. 33 to 37inclusive, vthe axle 5 is firmly connected to the vehicle and does notrotate. g

According to the arrangement shown in `Fig. 3S, three eccentric bearingrings 2, 3

and 4.- are connected by means of pivots 97 or the like With the `Wheelrim, for example by rodsand springs, the arrangement being Such that adead. 1091; cannot @teur between the -said parts because the axleautomatically assumes acentral position in its bearings.

The arrangement shown in Fig. 39 differs from that described Withreference to Fig. 33 in that the pivots 97 are mounted to slide inguides 98 on a member' y99 which is fixed on the axle, and is connectedto the Wheel rim in one or several places. lf, for instance, the member99 is of triangular shape as shown, the connection with the Wheel rimcan be `from its apex by means of links and springs.
